What Happened to LabVIEW NXG? And What to Use Now

If you have heard of LabVIEW NXG and wondered whether to use it, the short answer is: do not. NI discontinued active development of NXG in 2020. This page explains what NXG was, why it ended, and what to use instead in 2026.

What was LabVIEW NXG?

NXG LabVIEW (Next Generation) was NI's ground-up rewrite of LabVIEW, launched to modernize the editor and workflow. It was meant to eventually replace classic LabVIEW.

Why NI discontinued LabVIEW NXG

In 2020, NI announced it would stop active development of LabVIEW NXG and refocus on the classic LabVIEW line. NXG had not reached feature parity with classic LabVIEW, and large parts of the existing ecosystem, toolkits, and user base stayed on the original. Some NXG capabilities (like the web module) were carried back into other products, but NXG as a platform was wound down.

What this means for you

• •Do not start new projects in NXG. It is not the supported path forward.
• •Use classic LabVIEW if you are staying in the NI ecosystem. That is the line NI continues to develop. See what LabVIEW is.
• •Migrate off NXG if you have NXG projects, before support and compatibility erode further.

The bigger lesson

The NXG story is a reminder that betting your test infrastructure on a single vendor's roadmap carries risk. A discontinued platform can strand years of work. It is one reason teams increasingly favor open or portable approaches, Python for code, or vendor-agnostic platforms for automation, so a roadmap change does not orphan their tests.

Where TestFlow fits

TestFlow is built to be portable: validation plans and scripts use a vendor-agnostic layer rather than one proprietary environment, so your work is not tied to a single product's future. If the NXG experience made you cautious about lock-in, the free version is a low-risk way to try a different approach.
